8.0
The Power-Down mode is entered by executing a
SLEEP instruction.
Upon entering Sleep mode, the following conditions exist:
1.
2.
3.
4.
5.
6.
7.
8.
Refer to individual chapters for more details on
peripheral operation during Sleep.
To minimize current consumption, the following
conditions should be considered:
• I/O pins should not be floating
• External circuitry sinking current from I/O pins
• Internal circuitry sourcing current from I/O pins
• Current draw from pins with internal weak pull-ups
• Modules using 31 kHz LFINTOSC
• CWG, NCO and CLC modules using HFINTOSC
I/O pins that are high-impedance inputs should be
pulled to V
currents caused by floating inputs.
Examples of internal circuitry that might be sourcing
current include the FVR module. See Section 13.0
“Fixed
information on this module.
DS41586A-page 75
WDT will be cleared but keeps running, if
enabled for operation during Sleep.
PD bit of the STATUS register is cleared.
TO bit of the STATUS register is set.
CPU clock is disabled.
31 kHz LFINTOSC is unaffected and peripherals
that operate from it may continue operation in
Sleep.
ADC is unaffected, if the dedicated FRC clock is
selected.
I/O ports maintain the status they had before
SLEEP was executed (driving high, low or high-
impedance).
Resets other than WDT are not affected by
Sleep mode.

Preliminary
8.1
The device can wake-up from Sleep through one of the
following events:
1.
2.
3.
4.
5.
6.
The first three events will cause a device Reset. The
last three events are considered a continuation of pro-
gram execution. To determine whether a device Reset
or wake-up event occurred, refer to Section 6.11
“Determining the Cause of a Reset”.
When the SLEEP instruction is being executed, the next
instruction (PC + 1) is prefetched. For the device to
wake-up through an interrupt event, the corresponding
interrupt enable bit must be enabled. Wake-up will
occur regardless of the state of the GIE bit. If the GIE
bit is disabled, the device continues execution at the
instruction after the SLEEP instruction. If the GIE bit is
enabled, the device executes the instruction after the
SLEEP instruction, the device will then call the Interrupt
Service Routine. In cases where the execution of the
instruction following SLEEP is not desirable, the user
should have a NOP after the SLEEP instruction.
The WDT is cleared when the device wakes up from
Sleep, regardless of the source of wake-up.
8.1.1
When global interrupts are disabled (GIE cleared) and
any interrupt source has both its interrupt enable bit
and interrupt flag bit set, one of the following will occur:
• If the interrupt occurs before the execution of a
• If the interrupt occurs during or after the execu-
SLEEP instruction
- SLEEP instruction will execute as a NOP.
- WDT and WDT prescaler will not be cleared
- TO bit of the STATUS register will not be set
- PD bit of the STATUS register will not be
tion of a SLEEP instruction
- SLEEP instruction will be completely exe-
- Device will immediately wake-up from Sleep
- WDT and WDT prescaler will be cleared
- TO bit of the STATUS register will be set
- PD bit of the STATUS register will be cleared
External Reset input on MCLR pin, if enabled
BOR Reset, if enabled
POR Reset
Watchdog Timer, if enabled
Any external interrupt
Interrupts by peripherals capable of running dur-
ing Sleep (see individual peripheral for more
information)
cleared.
